WHEEL HUB.

Application led August 24, 1923.

This invention relates to machine elements and more particularly towheel hubs.

An object of the invention is to provide a unitary cast metal hub to beused in the construction of calf wheels and bull wheels.

An object is to provide a wheel hub of great strength and one requiringless labor in the assembly of parts for construction of the wheel.

An object is to provide a wheel hub of simple design and in whichsecuring bolts and nuts are easily accessible to facilitate assembly andseparation and to facilitate tightening up the parts and keep the wheelin goed condition at all times.

An object is to provide an interchange able wedging means adapted to beinserted between contiguous spokes of a pair.

Other objects and advantages will be made manifest in the followingspecification of an embodiment of the invention illustrated in theaccompanying drawings, wherein:

Fig. l is a section perpendicular to the axis of the hub.

Fig. 2 is an edge View of the hub showing applied spokes in crosssection.

Fig. 3 is a perspective of a butt end of one of the spokes.

The hub of the present invention includes a central cylinder box orsleeve 2 of such 'diameter as to snugly t an inserted shaft upon whichit may be shrunk and upon which it may be further secured as by radialset screws 3 and by radial rods or stud bolts 4. l,

Each end of the hub box 2 is provided with a disc or end plate 5 of anysuitable diameter and these are transversely connected by approximatelyradial webs 6 between contiguous pairs of which the set screws 3 havetheir heads exposed.

rThe periphery of the box 2 is provided with transverse recessed seats 7having a width approximating the thickness of spokes 8 adapted to beinserted in radial position and secured solidly against the webs 6.

A feature of the invention is to secure interlock between the spokes 8and the webs 6 and this is accomplished by providing lugs 6 on faces ofthe webs and by recessing faces of the spokes 8 as at 8a to receive thelugs 6a after the inner en'ds of the spokes have been jammed in theirseats 7 and then vinto register with the lugs 6a.

thrown so as to bring the lug apertures 8 This provides a substantialmeans for preventing outward movement of the spokes after they have beenapplied.

A feature of the invention is to provide an extremely simple,practicable and effective means for fastening the spokes 8 to preventlooseness and for solidly holding them in applied position in the hub.As here shown, such means includes a substantially wedge-shaped frame 10of suitable proportions and dimensions to obtain vthe desired strength.The converging opposite faces of the wedge frame l0 are adapted to bearupon contiguous faces of the inserted spokes S and the frames l()` haveytheir inner and outer walls perforated to receive the radial rods 4whose Jouter ends are threaded to receive nuts 4a and which are adaptedto bind down against the outer member of the contiguous frame and thusforce the frame radially inwardly and jam it against the spokes 8.

lt will be seen from the above that the invention consists of anextremely simple and substantial organization in which all of thefastening nuts, bolts and screws are readily accessible at any time toenable the quick tightening up and setting of the wedges and spokes.

What is claimed is:

l. A wheel hub comprising a sleeve adapted to be mounted about a shaft,means for securing said sleeve to the shaft, approxi-- mate-ly radialwebs secured to said sleeve, lugs formed upon said webs, spokes disposedadjacent said webs having recesses therein adapted to receive said lugs,wedge devices disposed between adjacent spokes adapted Yto maintain saidspokes adjacent their respective webs, and means for drawing said wedgedevices toward said sleeve.

2. A wheel hub comprising a sleeve adapted to be mounted about shaft,means for securing said sleeve to the shaft, approximately radial webssecured to said sleeve, lugs formed upon said webs, spokes disposedadjacent said webs having recesses therein adapted to receive. saidlugs, wedge devices disposed between adjacent spokes adapted to maintainsaid spokes adjacent their respective webs, means for drawing said wedgedevices toward said sleeve, and

flanges secured adjacent each end of said sleeve and bearingupon thesides, of said spokes.

3. A Wheel hub comprising a sleeve adapted to be slipped o n to a shaft,means for securing aid sleeve against `'rotation upon the shaft, angesformed integral with said sleeve adjacent the ends thereof,` ap-vproximately radial Webs integral Withsaidl sleeve and flanges, each webtogether With.

the adjacent web constituting a pair, spokes disposed adjacent theopposed faces of the Webs forming each pair, Wedge devices disposedbetween each pair of spokes engaging the opposed facestliereof, so as tomaintain said spokes adjacent their respective Webs, and means fortightening saidv Wedge devices toward said sleeve. j Y
